Letters Patent No. 98,199, dated December 2 1869.

The Schedule referred to in these Letters Patent and making part of thesame,

To all whom it may concern:

Be it known that I, JOHN P. SHERWOOD, of Fort v Edward, in the' countyotl Washiugton,-and State of New York, have invented a new, and usei'ulImprovement in Washing-Boilers; and l do hereby declare that thefollowing is a i'ull, clear, and exact description thereof, which willenable others-skilled in the art to make and use the same, referencebeingr had to the accompanying drawings, forming part ot' thisspecilication, in which- Figure l is a vertical longitudinal section ofmy improved boiler, taken through the line x x of iig. 2.

Figure 2 is a vertical cross-section of the same, t'ake'n through theline y y, tig. l.

Similar letters ot' reterence indicate corresponding parts.

My intention has for its object toimprove the construction ofthat classof washing-boilers in which the clothes are washed by the water as itboils, being projected down upon the clothes, to percolate through them,and thus-remove the dirt; and

It consists in the combination, with the perforated false-hottom, of theend discharge-spouts, of peculiar construction, as will be hereinaftermore fully described.

A represents an ordinary wash-boiler, about the construction ot' whichthere is nothing new.

B is a false bottom, which is placed a little above the bottom of thcboiler A, so as to leave a space -below it for the water.

The water-space below the false bottom B vis divided into twocompartments by the cross-partition C, the upper edgeof which isattached to the said false bottom B at or near its middle, and the loweredge of which rests upon the bottom otthe boiler AJ When the fire ishotter under one part or end ot' the boiler' than it is under the. othercud, the tendencyis for the water to be drawn toward vthe hotter end ot'the boiler, and be discharged through the spontat that end, leaving theother spout inactivo. The partition C guards against this temlency, andsecures the chculalitfn of the water through both spouts, thougl'iA involumes proportioned to the diti'erence in heat ofthe two ends oi' theboiler.

'lhe false bottom B is corrugated longitudinally upon each side of itscentral line, with two upwardlyprojecting corrugations, b', as shown inigs. l and 2,

extending from one endof said bottom to the other,

so as to form channels for the hottest part ot' the water and the steamto pass to the end spouts D.

The part ot' the false bottom B between and atthe sides ofthecorrugations b', is perforated with numerous holes, to allow the waterto vflow back freely to the space beneath the false bottoni B. s

The parts of the false bottom B toward its ends are vmade withoutperforations, so that bthe water may flow through said bottom only alongits middle part, thus introducing the cooler water over the middle orhottest part of the tire, 'and also preventing the cooler water frommingling with the water as it is abot passing up the ond spouts D. s y

The spouts D pass up the ends ot' thefboilerA, with the form of whichends the outer sides of the said spouts correspond. AThe innersides ofthe s'pouts D incline' outward, so that the said spouts may becomenarrower as they approach the top of the boiler The upper ends el of thespoutsD are inclined inward and downward, as shown in fig. l, and aremade broad and tapering.

The'under side ofthe inwardly and downwardlyprojecting parts d of thespouts D are corrugated, the said corrugations beginning at or near theangle or bend of the spouts, and gradually increasing in depth, until,'at the ends ofthe spouts, they touch the upper sides ot' the saidspouts, thus'dividing vthe streamsof water into a series of thin sheets,which, ilowing from the spouts at "the two ends of the boilers, meet,and are spread over theentire surface of the clothes, thoroughlyremoving thedirt from all their parts.

Having thus described my invention,

I claim as new, and desire. to secure by Letters Patent- A The two endsponts, D, having their inwardly-projecting upper parts d', constructedin the manner herein shown and described, in combination with the-corrugated and Aperforated false bottom B, substantially as and for thepurpose set forth.

`IJOHN l). SHERWOOD.
